Liu, X. AND M. Mullin. Presentation to the Spokane River Regional Toxics Task Force on Inadvertent Polychlorinated Biphenyl Sources, Fate and Transport and Preliminary Exposure Assessment. Spokane River Regional Toxics Task Force (SRRTTF) Meeting, Online, WA, February 22, 2023.
Impact/Purpose:
Although commercial polychlorinated biphenyl (PCB) production was banned in 1979 under the Toxics Substance Control Act (TSCA), inadvertent generation of PCBs (iPCBs) through a variety of chemical production processes continues to contaminate products and waste streams. The Spokane River Regional Toxics Task Force (SRRTTF), who leads efforts to reduce toxic compounds in the Spokane River in the United States (US), has requested regulatory change to restrict the use of iPCBs. This presentation is an outreach to SRRTTF on the progress of iPCB research conducted by the US Environmental Protection Agency research group. The research includes source identification, air emission, and dust migration studies and preliminary exposure assessment. The shared information will help SRRTTF for their risk assessment and management for iPCBs that entering the Spokane River.
